[0002] At present, there are many types of grinding system designs for food waste disposers on the market, but their structures are generally similar. They are all based on grinding discs and grinding rings with grinding hammers, and have been improved and optimized in different directions to improve the grinding effect and speed of food waste.

[0003] For example, the Chinese utility model patent "A grinding system for a kitchen waste disposer" with patent number 202320967186.2 and authorization announcement number CN219690666U includes a grinding cover with a grinding ring and a grinding disc installed in the grinding cover. The grinding disc rotates relative to the grinding ring under the drive of a driving mechanism. A grinding disc is fixed to the bottom of the grinding disc. A first curved portion with an opening facing upward is formed on the outer periphery of the grinding disc. The first curved portion extends outward from the outer edge of the grinding disc. The lower part of the grinding ring extends into the first curved portion with a gap left. A first blanking hole is opened on the first curved portion, thereby increasing the grinding area and effectively improving the grinding effect.

[0004] While the grinding effect is improved, the vibration and noise generated by the grinding system when processing kitchen waste are getting louder and louder, affecting the user experience. Utility Model Content
